The Coalition has announced that the Gears Of War 4 beta will begin on April 18th, at least for those who have early access. This early access is applicable to everyone who plays Gears Of War: Ultimate Edition using their account on either Xbox One or Windows 10 between now and April 11th. From the 18th players should receive codes to access the beta.
On April 25th the Gears Of War 4 beta will be opened up to Xbox Live Gold members, and it will run until May 1st. Last week information about Gears Of War 4 was revealed, confirming that the story is set 25 years after Gears 3, and will have players take control of Marcus’ son, JD Fenix. The Coalition also confirmed that the game would be inspired by the original’s foreboding atmosphere.
